    The flowers on this variety can be variable, and can appear in shades of white, yellow or purple. They are however usually a deep beetroot red. The other distinguishing feature of this variety is its plain green leaves, so choose this one if you are not a fan of leaf variegation. It is a native of east and north-eastern areas of North America and is very hardy.

    These plants are quite hard to grow and will take some time to establish large clumps, so they are better suited to the more experienced gardener.

  • Garden care: Plant rhizomes 5cm deep and 5cm apart in autumn. Once planted they are best left undisturbed so they can build up their numbers. Mulch in the autumn with a generous layer of leafmould.
  • CAUTION do not eat ornamental bulbs
